CHOPPER ATTACHMENT FOR CULTIVATORS.

Specification of Letters Patent.

Patented July 7, 1908.

Application filed February 12, 1908. Serial No. 415,577.

To all whom it may concern:

Be it known that I, CHESTER A, SNIDER, a

citizen of the United States, residing at Hennessey, in the county ofKingfisher and State of Oklahoma, have invented a new and useful Cho perAttachment for Cultivators, of which tlie following is a specification.

This invention has relation to chopper attachments for oultivators andit consists in the novel construction and arrangement of its parts ashereinafter shown and described.

The object of the invention is to provide a chopper adapted to be usedfor thinning out cotton to a stand and which is preferably in the formof an attachment which may be applied to the frame of a walking orsulkey cultivator.

The attachment consists primarily of a standard plate for attachmentwith a beam and upon which is journaled a disk, a .horizontally disposedblade is also attached to the said standard. A rearwardly disposed armis pivotally connected to the standard and is provided with means forfixing the same with relation thereto. Links are pivotally mounted uponthe rear end of said arm and are adapted to be adjusted laterally withmeans for fixing them in their adjusted positions. A supplementalstandard is ivotally connected with said links and a disk isjournaled-upon the last standard. Both of said disks are concave andtheir concaved surfaces are disposed in opposite directions. Anadjustable fender is pivotally mounted upon the arm and means isprovided for holding the fender in desired relation to the disk mountedupon the supplemental standard.

Figure 1 is a plan view of the attachment, and Fig. 2 is a sideelevation of the same.

The attachment is adjustably mounted upon the beam 1 which forms aportion of the frame of a cultivator or other implement. The standardplate 2 depends from the said beam and the concaved disk 3 is journaledfor rotation upon the said plate. The said plate is provided with arearwardly disposed eel ortion 4 and the blade 5 is fixed to the said lieel portion. The said blade is horizontally disposed and pitchedrearwardly at its outer end with relation to the line of draft. The arm6 is pivotally connected with the upper portion of thestandard 2 and maybe ad usted vertically and fixed in an adjusted end of the arm 6 and arearranged to be swung laterally and are held at a desired angle withrelation to the arm 6 by means of the clamp bolt 9. A supplementalstandard 10 is pivotally connected with the rear ends of the links 8 andthe concaved disk 11 is journaled for rotation upon the standard 10. Thecon cavities of the disks 3 and 11 are diposed in opposite directions.

The arm 12 is pivotally connected with the clamp bolt 9 below the lowerlink 8 and the bracket 13 is pivoted at the rear end of the arm 12. Thesaid arm 12 may be adjusted horizontally while the bracket 13 is free toturn horizontally The forward end of the fender 14 is ivotally connectedwith the bracket 13 am the rear end of the said fender lies opposite therear portion of the disk 11. The rear end of the fender 14 is free tomove vertically. The disk 3 is fixed at an angle to the line of draftwhile the disk 11 is disposed at an opposite angle to the line of draft.

From the foregoing description it is obvious that by adjusting the arm 6the disk 11 may be raised or lowered with relation to the disk 3 andblade 5. And by adjusting the links 8 laterally the disk 11 may be movedlaterally with relation to the disk 3; The arm 12 may be adjusted inorder to properly position the fender 14 with relation to the (isk 11.

When in operation for thinning cotton the attachment or two or moreattachments, as described, are drawn transversely across the row ofplants. The disk 3 will cut the roots and cast the soil away from thelants to be left standing. The blade 5 w' sever the roots of the plantsto be destroyed and the disk 11 will move the soil back against theroots of the plants left standing. The fender 14 prevents the soil frombeing cast by the disk 11 and thus the said disk in its operae tiop willnot cover the standing plants with s01 It is'obvious that by the variousadjustments provided that the disk 11 may be so positioned as to movemore or less soil as desired and also to operate at several degrees ofdepth below the surface of the soil or furrow and that it may be pitchedat such an angle with relation to the line of draft as to effectuallyperform its function undervarious conditions of soil. The attachment mayalso be used for cultivating crops, such as corn, sorghum etc.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

1. An implement of the character indicated comprising a standard, aconcaved disk journaled for rotation thereon, a horizontally disposedblade connected with the standard behind said disks, a concaved disklocated behind the standard and being connected with the same, saiddisks having their concavities disposed in opposite directions.

2. An implement of the character indicated comprising a standard, a diskjournaled for rotation thereon, a'blade fixed with relation to thestandard, a disk located behind the blade and being adjustably connectedwith the standard, and a fender located opposite the last said disk andmeans for adjusting the fender with relation to the said disk.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.

CHESTER A. SNIDER.
